如何在配置单元表中插入时间戳？

Question

hive> CREATE TABLE foo (bar timestamp) STORED AS ORC;
OK
Time taken: 0.041 seconds

hive> INSERT INTO TABLE foo VALUES ('2014-01-17 00:17:13');
NoViableAltException(26@[])

Answer 1

根据配置单元语言手册“插入...values在配置单元0.14中开始可用”。

因此，您只剩下两个选择：

1. 从现有表中插入时间戳值或调用函数获取该值（例如from_unixtimestamp())，请参阅以下答案）
2. 从文件中加载数据。
